I installed Netbeans then I tried to checkout my projects inside Netbeans. During the process Netbeans informed me something about an old client version of subversion, and now I want to upgrade it. But I don't know where the client is, nor how to update it.
BTW I have TortoiseSVN on the same machine and it works fine with the same repository, and as I use svn+ssh protocol, I configured Netbeans to use TortoisePlink.exe.
